Dust Devils on Mars

This morning we stumbled across this article in the Columbus Dispatch (written under contract by NASA), and we were reminded again of one of the cooler images to come from our solar system in the last few years.

The image is of a dust devil moving across a Martian plain on a hot spring afternoon a year ago:

 

The image was caught by NASA’s ‘Spirit’ Mars Rover in April, 2005. 

Both rovers (Spirit and Opportunity) have recently been upgraded with new software that enables them to better understand when a dust devil is moving across the martian surface, and to begin snapping pictures when they sense that movement:

NASA’s Space Technology 6 mission, or ST6, had already proven this "artificial intelligence" software in space. ST6 used it to help an Earth-orbiting satellite take pictures of erupting volcanoes on Earth. So NASA knew the software would help Spirit and Opportunity capture images of dust devils.

ST6 is part of NASA’s New Millennium Program, whose job is to test new technologies in space before putting them on NASA missions of discovery.

Other images and video from Mars can be found on NASA’s Mars Exploration Program website.
